About Matías

Software Developer with over 5 years of experience specializing in the PHP ecosystem (Symfony, Laravel) and Cloud architecture (AWS). I have a solid track record of leading complex integrations in regulated sectors and FinTech, including collaboration with Fever Finance on international tax regulations and the development of direct validation systems with the Tax Agency (Verifactu).

I optimize the software development lifecycle through AI Engineering dynamics. I use advanced models like Claude by designing system rules and structured prompts to automate efficient refactoring of legacy code, ensure strict adherence to DRY principles, and accelerate the delivery of new functionalities with high quality standards.

My experience encompasses comprehensive development cycle management using the Atlassian suite (Jira, Bitbucket), deployment of serverless solutions (AWS Lambda), system monitoring (CloudWatch), and evangelizing the team on QA strategies through the implementation of unit and integration tests.

In parallel, I actively participate in the growth of technology teams. I lead selection processes and conduct exhaustive technical interviews for Mid and Senior roles, evaluating both technical proficiency and adoption of best practices, as well as cultural fit within the organization.
